This study doesn't follow the usual testing phases — it may be an observational study or a different type of research.
This study is testing whether exercise during pregnancy—specifically aerobic exercise, resistance training, or a combination of both—can help reduce the risk that children will develop obesity later in life. Researchers want to understand which type of exercise works best for pregnant women and their babies' long-term health.
Childhood obesity often starts very early, even before birth, and can lead to serious health problems like heart disease in adulthood. This trial exists to find out what kinds of exercise pregnant women can safely do to give their babies the best chance at a healthy weight throughout their lives.

If you join, you will be assigned to one of three exercise groups: aerobic exercise (like using a treadmill or elliptical), resistance training (like weightlifting), or a combination of both. You'll exercise about 150 minutes per week at a moderate intensity level throughout your pregnancy. The research team will monitor your health and your baby's development during regular check-ins to see how the exercise affects both of you.
